Corollary  
Let \(G=N \rtimes H\)  be a Carnot group and we consider \(\delta _\lambda : G \rightarrow G\)  the usual intrinsic dilations \((\) see, for instance, [1]}\()\) .
Then \(\delta _\lambda \varphi \)  is an intrinsically \(L\lambda \) -Lipschitz section of \(\delta _ {1/\lambda }\pi _{N}\) , if \(\varphi \)  is so too for \(\pi _{N}\)  with Lipschitz constant \(L\) .
